Description

Technical Field

[0001] This invention relates to the field of infrastructure technology, and in particular to an integrated pile driver with side pile planting function. Background Technology

[0002] In many fields such as building construction, municipal engineering, foundation pit support, and slope reinforcement, pile driving is a fundamental and crucial construction procedure. Its core purpose is to stably implant precast piles, sheet piles, and other piles into the ground, providing reliable support, pull-out resistance, or lateral displacement resistance for subsequent engineering structures. In recent years, static pressure pile driving integrated machines have been gradually promoted in the market. These machines integrate the core static pressure pile driving device in the central area of ​​the pile driver, which can effectively complete pile driving in conventional open construction scenarios. However, as construction scenarios become increasingly complex and diverse, especially in urban core area renovation and building perimeter reinforcement, pile driving operations often need to be carried out near walls, fences, existing building foundations, or other obstacles. In these cases, the structural defects of placing the static pressure pile driving device in the middle become apparent. Due to the pile driver's own size and lateral extension range, the machine's structure may interfere with and collide with walls and obstacles, preventing the internal static pressure pile driving device from approaching the preset pile driving point to complete the operation.

[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention proposes an integrated pile driver with side pile planting function to solve the problem of side pile planting.

[0005] To solve the above-mentioned technical problems, the solution adopted by the present invention is as follows: an integrated pile driver with side pile planting function, including a chassis and a column rotatably mounted on the chassis. A pulley seat is provided at the top of the column. A first power head and a second power head are respectively slidably mounted up and down on the column. A first drill rod is detachably mounted at the lower end of the first power head, and a second drill rod is detachably mounted at the lower end of the second power head. A static pressure pile planting device is provided in the middle of the chassis. A side pile planting device for planting piles close to obstacles is detachably mounted on the chassis directly in front of the column. A traveling mechanism for rapid left-right movement and fine-tuning forward-backward movement is provided below the chassis. The side pile planting device includes a base, a lifting seat, several first clamping blocks, a lifting piston cylinder, and a first clamping piston cylinder. The base is detachably mounted on the chassis and is rectangular in shape, narrow at the front and back and wide at the sides. The four corners of the base are supported by pillars. The lifting seat is located above the base. Each of the four corners of the lifting seat has a lifting opening that fits and moves with the surface of the pillar. The tops of the two pillars at the front end of the base and the tops of the two pillars at the rear end of the base are connected to a crossbeam. The front and rear ends of the lifting seat are connected by an installation channel below the crossbeam. The cylinder body of the lifting piston cylinder is fixedly installed in the installation channel, and the free end of the piston rod of the lifting piston cylinder is fixedly installed on the crossbeam. The middle of the lifting seat has a first clamping channel, and the base has a second clamping channel. The cylinder body of the first clamping piston cylinder is fixedly installed at the left and right ends of the lifting seat, and the first clamping block is located in the clamping channel and fixedly installed on the piston rod of the first clamping piston cylinder.

[0006] A further improvement is that the base is provided with a second clamping block and a second clamping piston cylinder. The cylinder body of the second clamping piston cylinder is fixedly disposed at the left and right ends of the base, and the second clamping block is located in the second clamping channel and fixedly disposed on the piston rod of the second clamping piston cylinder.

[0007] A further improvement is made to the base, which is equipped with a rear limiting device to compensate for the lack of clamping force in the forward and backward directions and improve the verticality of the pile. The rear limiting device includes a limiting post, and two U-shaped plates are provided on the lower surface of the chassis. A sliding channel is formed between the U-shaped plates and the chassis. The limiting post slides through the two sliding channels. The front end of the limiting post is provided with an arc-shaped limiting surface for partially wrapping and fitting the surface of the precast pile to restrict its forward and backward rotation. The rear end face of the base is provided with a limiting opening for the limiting post to extend into the second clamping channel. The upper end of the second clamping block is provided with an avoidance notch for the limiting post to insert when the second clamping block clamps the precast pile. The limiting post is equipped with a sliding drive device for driving itself to slide forward and backward.

[0008] A further improvement is made to the sliding drive device, which includes a fixed base and a sliding piston cylinder. The limiting post has an internal mounting cavity, the sliding piston cylinder is disposed in the mounting cavity, the piston rod of the sliding piston cylinder is hinged to the rear end of the mounting cavity, the fixed base is hinged to the bottom of the sliding piston cylinder, the upper end face of the limiting post has a sliding opening for the fixed base to extend and slide, and the upper end of the fixed base is fixedly disposed on the chassis.

[0009] A further improvement is that: a first mounting lug is horizontally provided on each of the four corners of the rear end face of the base, and a second mounting lug is provided on the outer end face of the first mounting lug on the chassis, and a fixing shaft is longitudinally provided through the first mounting lug and the second mounting lug.

[0010] A further improvement is that: the left and right sides of the base are respectively provided with adjustment structures between them and the chassis for adjusting the left and right tilting position of the base and increasing the installation strength of the base; the adjustment structure includes an adjustment piston cylinder, a first mounting seat, and a second mounting seat. The first mounting seat is fixedly mounted on the chassis, the bottom of the adjustment piston cylinder is hinged to the first mounting seat, the second mounting seat is hinged to the piston rod of the adjustment piston cylinder, and the second mounting seat is detachably mounted on the side of the base.

[0011] A further improvement is that reinforcing rods are provided between each pair of the upper ends of the support pillars.

[0012] A further improvement is that the bottom of the lifting seat is fixedly equipped with a support foot to prevent the bottom of the lifting piston cylinder from hitting the base.

[0013] A further improvement is that the walking mechanism includes a roadbed walking assembly and a track walking assembly. The roadbed walking assembly is arranged in the left-right direction at the front and rear ends of the chassis, and the track walking assembly is arranged in the front-back direction at the left and right ends of the chassis.

[0014] A further improvement is that the chassis is equipped with a hoisting frame for hoisting precast piles into the static pressure pile-planting device.

[0015] A further improvement is that a control room is provided at the rear of the chassis.

[0016] A further improvement is that the chassis is equipped with counterweight boxes on both sides of the control room for balancing the chassis.

[0017] By adopting the aforementioned technical solution, the beneficial effects of the present invention are: 1. The side pile planting device is installed directly in front of the chassis column, allowing for pile planting close to obstacles and avoiding collisions or interference between the pile driver and obstacles. The chassis of the side pile planting device is rectangular, narrow at the front and back and wide at the sides, maximizing the distance to obstacles and allowing the clamping channel of the side pile planting device to be closer to the obstacles. The first and second clamping blocks, in conjunction with the chassis shape, are only located on the left and right ends of the side pile planting device, making the front-to-back dimensions of the side pile planting device more compact and facilitating closer proximity of the clamping channel to obstacles. Combined with the tracked walking component in the pile driver's walking mechanism for fine-tuning movement in the front-to-back direction, the planting position can be further precisely adjusted, ensuring that precast piles can be planted at preset obstacle-close points, overcoming the shortcomings of traditional pile drivers' structures that are inconvenient for side pile operations.

[0018] 2. In the side pile planting device, the cylinder body of the lifting piston cylinder is fixed within the installation channel of the lifting base. The free end of the piston rod is directly connected to the crossbeam. The structure and extension stroke of the piston rod are entirely within the space between the base and the crossbeam, without extending additionally upwards towards the crossbeam, making the overall structure of the side pile planting device more compact. This also reduces the possibility of the lifting piston cylinder being damaged by collisions with obstacles during operation and by collisions with surrounding objects during storage, thus protecting the lifting piston cylinder and extending the service life of the side pile planting device.

[0019] 3. To make the clamping channel of the side pile planting device closer to the obstacle, the clamping blocks are only set at the left and right ends of the side pile planting device, which compromises the stability of the clamping and easily causes an imbalance of force on the upper and lower ends of the precast pile. This makes the precast pile prone to overturning due to unilateral force during planting. The second clamping block and the first clamping block are distributed vertically along the precast pile to form two clamping points at the top and bottom. When the lifting seat moves the precast pile clamped by the first clamping block downwards under static pressure, the second clamping block restricts the movement of the lower end of the precast pile but does not clamp it. Before the lifting seat rises, the first clamping block and the second clamping block exchange clamps, that is, the second clamping block clamps the precast pile and the first clamping block releases the precast pile, which helps to improve the verticality of the precast pile planting.

[0020] 4. The arc-shaped limiting surface of the limiting column always fits the surface of the precast pile during the pile planting process. The arc-shaped limiting surface has a certain height, which further restricts the precast pile from turning back and forth, improves the verticality of the precast pile, and avoids the precast pile from damaging the geological structure under the nearby building.

[0021] 5. The side pile planting device and the pile driver chassis have a certain assembly error after assembly. However, the symmetrical adjustment structure is set on the left and right sides of the base, allowing for calibration of the coaxiality between the clamp channel center and the planting hole center without disassembling and reassembling the device. By controlling the extension and retraction of the piston rods of the left and right adjustment piston cylinders, the left and right deflection angle of the base can be finely adjusted to correct the assembly error of the side pile planting device. This also ensures the overall stability of the device during the planting process, preventing left and right swaying. Attached Figure Description

The lifting seat 24 is positioned above the base 23. Lifting openings 33 are provided at each of the four corners of the lifting seat 24, allowing it to move and lift in contact with the surface of the support columns 31.

[0033] The base 23 is provided with a rear limiting device to compensate for the lack of clamping force in the front and rear directions and improve the verticality of the pile. The rear limiting device includes a limiting post 41. The lower surface of the chassis 10 is provided with two U-shaped plates 42. The U-shaped plates 42 and the chassis 10 form a sliding channel 43.
